Justin Bieber may seem totally loved up with Hailey Baldwin but he hasn’t forgotten about his hot romance with Kourtney Kardashian. A source tells HollywoodLife.com that Justin still has feelings for Kourtney but will he drop Hailey for the mom-of-three?

Justin Bieber is a master juggler … of women! The 21-year-old has his hands full with Hailey Baldwin, Kourtney Kardashian and his drama withSelena Gomez. A source tells HollywoodLife.com that even though Justin’s cup runneth over when it comes to his pick of Hollywood women, he has zero plans to give up on any of the leading ladies, especially 36-year-old Kourtney and we know why!

“Justin’s not done with Kourtney, not by a long shot!” a source tells us. “He’s keeping her in his rolodex of women. She offers him stability and that’s huge for him. She’s mature, she’s grown and sexy and she’s not all crazy emotional like the other women he’s use to dealing with. She’s a smoking hot milf and unlike Finch in the movie, this is real life for Justin.” But why is Justin continuing to woo Kourtney when he just spent a romantic vacation with Hailey over New Year’s? “Justin still can’t believe her was able to pull Kourt in the first place. He really thought that she was completely out of his league. Being with her has given him crazy confidence and there’s no turning back. Kourt doesn’t really know what she’s got herself tangled in.”

But Kourtney isn’t taking Justin’s major PDA pics with Hailey too well. “Kourtney wants a major explanation and apology. She’s not the one who leaked their romance to the public. She feels like she’s being punished and it just goes to prove her initial instinct that Justin is too young and too immature for her,” the source continues. “She’s kind of beating herself up for ever getting involved with him in the first place, and not listening to her gut. She really regrets the whole thing.”
